Solved Color on signs

Hi.
I'm trying to put color on my signs, with a variable that hold the colors. But for now, Eclipse tells me that there is a syntax error. Code :

Code:

                sign.setLine(2, BattleType(world));
                ChatColor color;
                if (worldplayers < MaxPlayers(world) / 4) {
                    color = ChatColor.BLUE;
                }else if (worldplayers < MaxPlayers(world) / 2) {
                    color = ChatColor.DARK_GREEN;
                }else if (worldplayers < MaxPlayers(world) / 4 *3) {
                    color = ChatColor.YELLOW;
                }else {
                    color = ChatColor.RED;
                }
                sign.setLine(3, color worldplayers + "/" + MaxPlayers(world));
                sign.update();

 

It's because color (or ChatColor.something) is a string, so at line

Code:java

sign.setLine(3, color worldplayers +"/"+ MaxPlayers(world));

you're not joining two strings, color and worldplayers, so you have to put + character between them

is it that? Maybe it'll help to show what error you have. It could be anything.

 

@PDKnight @teej107 It's not, if I do this it says :"The operator "+" is undefined for the arguments type(s) ChatColor, int".

 

Hm, try to do

Code:java

sign.setLine(3, color + (worldplayers+"") +"/"+ MaxPlayers(world));

 

@PDKnight Worked, thanks !

 

@Betagear

I don't really understand how that message is ambiguous at all.

And it's really sloppy to do it that way. Use toString() on the ChatColor and it will work fine.

@PDKnight

No, ChatColors are not Strings, they are enums with a toString() method that is implicitly called by concatenating them with Strings. There is a difference.

 

@Betagear
If you want to add different objects to the same piece of text, you need the + char. What you currently have is the object color and the object world players "mixing" into one.

 

@mythbusterma Thanks for explanation
